Proximity Sensors are designed to detect and respond to movement outside of the component and within the range of the sensor (0” (0 mm) to 50’ (15.2 m)). The sensor types include capacitive, inductive, infrared, light, and ultrasonic with output types of analog current, voltage, configurable, I2C, NC, NO, NPN, 2-wire, 3-wire, 4-wire, 5-wire, PNP, push-pull, relay, requires amplifier, and SCR.

Compare SPST and SPDT toggle switches, understand AC/DC ratings, and follow wiring examples. Check contact action, mounting and parts in the ChipApex catalog.
